The list of participants can be downloaded at a completed instant or scheduled event.
There are three dots to the right of the event name. Click on it and in the menu select the “Download list of participants”.

In the list - name, surname, and email is downloaded as a CSV table.
 
Please note: that due to the simplified authorization the participant should only enter a name. For the list of participants to be visible by email - participants must be invited by email.
 
For permanent rooms, the list of participants cannot be downloaded - all data is cleared after the event.
